NOAA 2222 developed close to the southeast limb and is actively flaring. It was responsible for at least 10 C-class flares, including a C8.2 flare peaking at 00:47UT which was the strongest event of the observing period. Departing region NOAA 2209 was the only other region to produce a C-class flare. The other regions were quiet, with NOAA 2219 having some mixed polarities. The x-ray background flux increased from about B9 to nearly C2. A filament eruption was observed in the NW quadrant around 16:00UT on 26 November. A slow CME first observed in LASCO/C2 at 17:36 may have been associated to it. The other filaments were quiet. None of the observed CMEs are directed to Earth. Low-level M-class flares are possible. A sector boundary crossing (SBC) occurred around 03:00UT. IMF turned towards the Sun. Solar wind speed gradually increased from about 300 to 400 km/s. Bz varied between -7 and +9 nT, but was mostly positive after the SBC. The geomagnetic field was quiet. Geomagnetic conditions are expected to be quiet to unsettled, with an isolated active period not excluded.
